A relatively affordable 23.8-inch monitor from the AOC brand is a versatile solution with Full HD resolution. This model is a good match for a budget computer intended for office work or study, and can also be used at security desks (for displaying images from surveillance cameras) and more. The display is based on an IPS panel with support for 8-bit color depth (16.7 million shades).
It is notable for its increased refresh rate of 120 Hz and moderate response speed (4 ms gray-to-gray), making it recommendable for casual gaming. The AOC 24B31H monitor features fairly standard contrast and brightness — 1500:1 and up to 300 nits, respectively, and benefits from wide viewing angles, which is a typical advantage of IPS technology. The model should not strain your eyes, as it supports flicker protection and the proprietary Lowblue Light function, which reduces intense blue light to protect vision. Before purchasing, keep in mind that it comes with a basic stand (allows only display tilt adjustment) and not the most advanced video signal interfaces — VGA and HDMI 1.4. It's also worth noting that within the brand's Home series, there is a related solution with a 27-inch screen diagonal — the 27B31H.
